The #JunoMission spacecraft successfully completed its 47th close pass by Jupiter on Dec. 14, but an on-board computer issue disrupted the downlink of data collected during the pass. Juno is healthy, and the team expects to complete the full downlink soon: missionjuno.swri.edu/news/juno…

Currently, old satellites either burn up safely in the atmosphere or remain in space. But we're working on new technology that could refuel or upgrade satellites while in space, expanding their lifespans and making spaceflight more sustainable: go.nasa.gov/3WCtVir

Great, now stop Musk from polluting LEO with his 50,000 Starlink satellites. Why does a billionaire get free reign over our limited space resources???
in reply to NASA

@nasa. That’s great but won’t fixing the old satellites be akin to rehabbing a 1965 Rambler as opposed to driving a new Audi? Fix up old junk and you end up with fixed up, obsolete junk.

Early warnings on floods can save lives, but roughly half of the world's countries lack adequate early warning systems.

That's about to change, thanks to a new tool developed by @nasa and the Pacific Disaster Center (PDC).

This is the first time comprehensive global flood early warnings at the sub-watershed level have been possible.

Thanks to MoM and DisasterAWARE, small and vulnerable communities now have a powerful new tool to take early action on flooding and protect lives and livelihoods.

#OTD in 1964, NASA's SR-71 Blackbird made its 1st flight.

The SR-71 was designed to cruise at Mach 3.2 and at altitudes up to 85,000 ft, making it ideal for high-speed, high-altitude @NASAaero research.

I'm all for space exploration and NASA...however, "Space for Peace" (parallel to "Atoms for peace).
This is a prime example and only one - recasting the intelligence (spy) SR-71 plane as a NASA research vehicle.

Still amazing to consider humans repairing equipment in outerspace, with all the dangers that involves.


About an hour into the spacewalk, Cassada is working to release the anti-rotation devices on the iROSA that are holding it in place. Rubio is securing power cables that will be connected once the iROSA is in place and making sure the soft-capture system is ready for its arrival.

Can you explain how these tubular samples can await retrieval on the Mars surface without threat of dust storms covering them up? I assume the vials have trackers, but can we be sure a future mission includes no-fault retrieval tools?
