NASA was able to provide key guidance on how to best comply with strenuous space certification, safety and operational requirements, and Made In Space excelled at incorporating that insight into the design,***8221; noted Niki Werkheiser, NASA***8217;s 3D Print project manager. ***8220;As a result, the hardware passed testing with flying colors.***8221;

3D Printing is a maturing technology and should eventually provide the ISS with the ability to ***8220;print***8221; a select amount of replacement parts, in situ. This technology will be vital for future explorers in deep space, where ISS-style cargo runs won***8217;t be readily available.

SpaceX is also a big fan of 3D printing, with parts for the SuperDraco thrusters on the Dragon V2 ***8220;printed***8221; in this manner. L2 sources also note that parts for SpaceX***8217;s next generation engine, the Raptor, are currently being 3D printed at the company***8217;s Hawthorne base in California.

That engine, part of the company***8217;s own deep space aspirations, is for the future, with the current focus on continuing to press through their large order book, providing services for their commercial customers and NASA.

SLS searching for missions to solve flight rate dilemma | NASASpaceFlight.com

Quote:
As has been the case for a number of years now, only two missions are currently manifested, while her projected schedule in the 2020s remains threadbare.

The issue of the flight rate for SLS was known even before the rocket was officially announced, with a stuttered start mainly caused by political language.

The requirement for debuting SLS in 2017 had little to do with the rocket’s Beyond Earth Orbit (BEO) exploration aspirations. It was the 2010 Authorization Act that called on SLS and Orion to provide a back up role to the Commercial Crew Program, in the event of a severe delay to what is now known as the USCV-1 (US Crew Vehicle -1) mission.

Ironically, SLS’ multi-billion dollar strain on the NASA budget has indirectly starved Commercial Crew funding, resulting in USCV-1 slipping to at least the end of 2017.

Also adding to the irony was the fact SLS and Orion were never likely to provide such a back up role, due to the obvious requirement the first SLS mission having to be uncrewed for safety reasons. The last time a crew rode on the debut of a NASA vehicle was in 1981, during Columbia’s STS-1 launch.

Notably, such a SLS and Orion mission to the ISS would have likely cost more money than it would to accelerate the Commercial Crew USCV-1 launch date.

The fallout of this political requirement for SLS to launch in 2017 was never solved, even when NASA made it clear Orion had been fully refocused on BEO missions. The result was a four year gap between the debut flight of SLS and the second mission, a flight that will involve a crew for the first time.

Although this schedule remains the case via public statements by NASA, internally Exploration Mission -1 (EM-1) has slipped to at least the middle of 2018.

Notably, the slip is specific to Orion’s schedule issues, with some sources noting SLS may still launch in 2017 on a test flight with either a dummy payload or a boilerplate Orion. However, this is just one of several options under consideration.

What remains the most likely scenario is a 2018 launch of EM-1, with Exploration Mission -2 (EM-2) accelerated to the end of 2020, as continues to be portrayed by internal documentation.

Once SLS is into the 2020s, the launch rate should see the rocket launching at least once per year, ramping up to a projected three times per year for the eventual Mars missions. However, the latter won’t be until the 2030s.

With no missions manifested past the EM-2 flight, the undesirable question of just how “slow” a launch rate would be viable for SLS and her workforce has now been asked.

“Everyone recognizes that safety issues can be induced with a fast launch rate; however, if the launch rate is too slow, people skills, processes, and equipment can degrade,” as was noted at the latest Aerospace Safety Advisory Panel (ASAP) meeting. “Generally, there is an optimum launch rate with some limits on ‘too fast’ or ‘too slow.’”

It was then revealed to the meeting that “The (SLS) Program has considered this conceptually and has some ideas on how slow is too slow.”

It is understood that NASA believes one launch every two years is “too slow” and over two launches per year is “too fast” for missions in the 2020s, based on current SLS production limitations.

In response, the ASAP encouraged the SLS Program to pursue this question and determine what the boundaries are, before references were once again noted about potential science missions.

“Budget limits will put pressure on launch rates,” the meeting notes continued. “One thing that may help the launch rate is the growing interest by the science community in using the SLS for science missions.

“One possibility that has arisen is the Europa mission. Missions like this can help fill the gaps and provide a safe and cost-efficient launch rate beyond a human mission to Mars.”

Such a mission with a spacecraft bound for Jovian moon Europa would be an even larger challenge to enable, mainly from a funding standpoint.

However, it has been on the radar of SLS managers as one of the more steadfast attempts to attract science missions to their manifest, with previous L2 notes showing they have been working alongside the Jet Propulsion Laboratory (JPL) on a notional science mission to the Europa. However, this was an exercise, as opposed to the opening plans for an action mission.

Since then, a Europa mission has continued to be cited in both L2 and public documentation, including the more recent NASA Advisory Council (NAC) overview on SLS’ status.

“Europa exploration was identified as a high priority in the ‘Visions and Voyages’ planetary science decadal survey. SLS can provide direct injection to Jupiter, eliminating several years of planetary gravity assists to reduce flight time to Europa from 6.3 years to 2.7,” noted the latest NAC presentations.

“Additional benefits of SLS for Europa Clipper include reduced operational costs, reduced mission risk, and greater mass margin.”

Internal evaluations have also placed the Europa mission as a potential addition to the manifest for the SLS Block 1B – the 105mT version of the Heavy Lift Launch Vehicle (HLV) – a configuration that is set to dominate the 2020***8242;s SLS manifest and potentially beyond.

Known as the “Three Degrees Of Freedom (3-DOF) Reference and Loads Trajectories” evaluations, a Design Analysis Cycle (DAC) noted “Design Reference Missions (DRMs) addressed include the Europa mission configuration (27500),” per L2 notes.

Incidentally, it also involved two “Lunar mission configurations (27002 cargo and 28002 crew),” which sources note is related to any potential change to the current political direction, one that is currently shunning a return to the Lunar surface.

“Two loads trajectories (maximum dynamic pressure and maximum acceleration) were also generated for each DRM. The 3 reference and 6 loads trajectories will be presented to the Structures and Environments (StE) Ascent Flight Systems Integration Task Team (AFSITT).”

Also previously shown to be under evaluation is SLS’ involvement in a Mars Sample Return (MSR) mission.

The evaluations depicted, the “2024+ Single Shot MSR on SLS is based on “launch cadence and availability providing a single-shot Mars Sample Return opportunity.”

This would not be a primary mission for SLS, with the “Mars SEP (Solar Electric Power/Propulsion) Orbiter” riding as a secondary payload. The cited alternatives of using a Falcon Heavy or a Delta IV-Heavy would see it become their primary payload, if selected.

Based on such a projected timescale for the mission, the opportunity falls into the domain of SLS-5 or SLS-6, should the current manifest remain unchanged.

Such a notional overviews involve Orion being used on the second leg of the mission, picking up the samples in space.

The idea was again touted in the recent NAC documentation, this time claiming the alternative vehicles would require multiple launches to achieve.

Mars Sample Return was identified as a high priority in the ‘Visions and Voyages’ planetary science decadal survey. SLS offers single-launch option for Mars Sample Return, versus three launches with EELVs,” the NAC presentation claimed.

“Additional benefits of SLS for Mars Sample Return include reduced mission time, increased sample mass, and reduced mission cost, complexity and risk.”

Such claims are repeated for various other notional missions, including large probes to various deep space destinations. However, no such mission will become a reality without funding.

Officials are yet to note how factoring in the cost of the SLS program impacts on the likelihood of such science missions ever becoming a reality.
tl;dr?
get congress to double nasa spending to 1% of gdp from .5%,. Basically from 18 billion to 36 billion, still way under 50 billion given to the NRO (spy sats) and we can do anything we ever wanted

or do what we're doing now and remain hamstrung forever

Sea plankton 'found living outside International Space Station' - Telegraph



Sea plankton has been discovered living on the outside of the International Space Station, Russian cosmonauts have claimed. Scientists on board the ISS are reported to have discovered living organisms when taking samples from windows. Head of the Russian ISS orbital mission Vladimir Solovyev said the results of the experiment ***8220;are absolutely unique***8221;. Solovyev told the Russian Itar-Tass news agency that the tiny marine life-forms were not native to the launch site in Kazakhstan.

***8220;Plankton in these stages of development could be found on the surface of the oceans,***8221; he said. ***8220;This is not typical for Baikonur [in Kazakhstan]. It means that there are some uplifting air currents which reach the station and settle on its surface.***8221;

why lol?

also nice source
NASA, Russia Squabble Over International Space Station Sea Plankton Claim - Forbes
Quote:
***8220;As far as we***8217;re concerned, we haven***8217;t heard any official reports from our Roscosmos (Russia***8217;s space agency) colleagues that they***8217;ve found sea plankton,***8221; NASA spokesman Dan Huot told Space.com. ***8220;What they***8217;re actually looking for is residues that can build up on the visually sensitive elements, like windows, as well as just the hull of the ship itself that will build up whenever they do thruster firings for things like re-boosts. That***8217;s what they were taking samples for. I don***8217;t know where all the sea plankton talk is coming from.***8221;

NASA scientists report that it***8217;s possible the reported sea plankton could be a contaminant that hitched a ride from Earth when the space station modules were launched. Previous research has also found that certain tiny species ***8212; known as extremophiles ***8212; can survive in space and other harsh environments. Just today, new research is being published in the journal Nature that documents the discovery of microbes living beneath a half mile of Antarctic ice without any access to sun or wind.

If the cosmonauts truly did discover sea plankton hanging out in space, it could have interesting new implications for how we view life***8217;s compatibility with the rugged environment that is space; or it might just mean that plankton is a lot tougher than previously expected.

hey i got some news about planets outside the solar system
apparently they have clouds, lots of them do
and we are starting to take actual visual light spectrum photos of some of these planets which is great cuz current methodology only allows us to see hot planets, and we need to be looking for cooler ones like earth, cuz earth is cool you see?

Goshin, come to the dark side. Clouds and pictures of planets outside our solar system is chinese torture, like looking for drops of water on Mars in between spectrometer readings of wrecked machinery.

Im telling you, your favorite senator from Arizona has already proved to the public that there is a problem with a robot that has 20 cameras and been roaming for 2 years and has only produced 20 photos. something is up.

Just today I was reading about how a company reverse engineered more of the space glass which generates electricity but is perfectly transparent. Glass is the next metal, they've known that for 40 years!!

why are all the machines on Mars made of steel?

Thousands at varying levels of resolution, and they've been caught, more than once with UFO's on screen.

John McCain made them release additional photos. Everyday there is an article fearmongering the public into thinking the poor rover is going to hit a rock and die. Meanwhile they are amassing who we are, where we came from and where our space technology is headed. There was recently an experiment regarding field propulsion, something the ancient civilization mastered.

NASA has never denied it, FYI, they quietly acknowledge the grey areas. Like the lava domes on the moon. Why aren't people discussing the possibility of making a base, or a city underneath them? They don't know they exist, because NASA releases an obscure article about it while there is another hot news item.

If they were not afraid why did they airbrush them out to begin with? Several of the moon mission photos were taken in front of these lunar domes.

so this post is geared more towards our shop heads out there
lots of technical speak on getting the new solid rockets ironed out after finding issues in the insulation. It's pretty interesting in what they had to do to figure it out and (looks like) fix it

the other article discusses the gigantic welding machine (170ftx48ft) built in new orleans to put together the SLS core including dome welding, ring welding and other kinds of welding i assume
Michoud proudly reveal monster welder for SLS cores | NASASpaceFlight.com

since both are highly technical and only discuss those topics on depth, i'm just providing summary. click the links for really cool photos of both and a great read!

yea, it launched asianet8 a few weeks before that
but they havent been doing any more reusability tests
that'll come on the next crs mission soon so i was holding off on reporting any and all flights unless they did something new

its a pretty photo tho

that was an indication that their range safety device worked as intended
there was an anomaly so they blew it up
first time ever doing so and they were pressing the limits of the machine so gg

that was also a test vehicle, not a launch vehicle

monumental difference
