This could be related. :smile:

"The location of the plumes corresponds to the position of an unusually warm spot on the moon's icy crust, as measured in the late 1990s by NASA's Galileo spacecraft . Researchers speculate that this might be circumstantial evidence for material venting from the moon's subsurface. The material could be associated with the global ocean that is believed to be present beneath the frozen crust. The plumes offer an opportunity to sample what might be in the ocean, in the search for life on that distant moon."

Dust...



The problems you run into, in outer space.


Wondering if this is serendipity, or did someone know this?

A SpaceX launch is upcoming, 11:00 to 13:00 UTC (9-11 hours after this post). The first stage will land on the ground pad. It is a military satellite, no details about it are known, not even the target orbit (although I'm sure many amateurs will quickly track it). This also means we won't get a video of the second stage, but we can watch the first stage return to Cape Canaveral.

Livestream

Edit: Shifted to tomorrow due to an issue with the first stage.

Edit2: Looking good so far, at T-0:17:00.

Edit3: Success!
Well, they didn't show the second stage, but at least the first stage worked nicely and landed again, and I guess they would report a loss of mission.

NROL-76 footage has the first complete uninterrupted video of first stage flight, through MECO, boostback, flyback and landing. And it's jaw-dropping.

This should be an interesting launch to follow, a lot of new systems designs going on with "It's a test"
https://spaceflight101.com/launch-week-arrives-for-rocket-labs-electron/
"Rocket Lab’s Electron is targeting liftoff between May 24 and June 2 with daily windows stretching from 1 through 5 UTC, 1 - 5 p.m. local time at the company’s launch facility at Mahia Peninsula on New Zealand’s North Island."

As far as I know, it will be the first orbital launch from the southern hemisphere.
The British launched a few sounding rockets from Australia and New Zealand, and Argentina/Brazil launched a few from Brazilian spaceports, but none of them went to orbit.

That is what I understand also, a first from the southern Hemisphere.
Also I've been waiting for this for a long time.

"Scientists from NASA's Juno mission to Jupiter will discuss their first in-depth science results in a media teleconference at 11 a.m. PDT (2 p.m. EDT) Thursday, May 25, when multiple papers with early findings will be published online by the journal Science and Geophysical Research Letters."

Here is a good example of aerospace engineering at its finest, definitely a "one of a kind" Aircraft.
http://spacenews.com/stratolaunch-rolls-out-giant-aircraft/
"The Stratolaunch aircraft is the largest in the world by wingspan, measuring more than 117 meters from tip to tip. The plane weighs 226,800 kilograms empty, and 50 percent more when fully fueled. It can accommodate payloads weighing nearly 250,000 kilograms, attached to the wing segment between the twin fuselages. - See more at: http://spacenews.com/stratolaunch-rolls-out-giant-aircraft/#sthash.VehuLlpr.dpuf"

Still a 60% chance of launch for CRS-11 today, This ones a first for the reused Dragon, also the NICER will make a great addition to the ISS.

I can't seem to find a link for the technical webcast, that may be because NASA tv is also covering the launch.

SpaceX merged both webcasts to one. Edit: There is still a separate webcast, see below.
In terms of launch time and trajectory, large parts of Europe have a good chance to see both Dragon and the second stage. I made a thread. The weather, on the other hand, ... cloudy nearly everywhere.

That is a shame, I thought the technical webcast was much better than the hosted. NASA is devoting considerable time on their site but seem to be spreading it out over several hours. Curious how their launch coverage will differ from the youtube webcast.

I have been watching it, very cool idea, I've often wondered what it would look like or if it would even be visible from Europe. On Sunday evening I get a very good 5 minute pass and I'll watch to see if Dragon is visible as it goes over.

:ok: Nice landing. they are making that part look easy
 
  • #262
Yeah, landing is getting routine.
In a year reflights will get routine.

True enough, hope it doesn't get to the point that routine leads do extra risk. Any word on visibility from Europe?
 
  • #264
Had a thick cloud cover, I didn't even try to see anything.
Routine should lead to a lower risk.

Upcoming spaceflight stuff:

India will have the maiden flight of a bigger rocket on Monday, 4 ton payload to GTO, about half the Falcon 9 payload.

Next Falcon 9 flight: June 15, a booster recycled from the January launch.

It appears that SpaceX is serious about the "competition is good for business" thing.

http://money.cnn.com/2017/06/07/technology/future/spacex-air-force-launch-contract/index.html
"SpaceX has won an Air Force contract to launch a secretive, unmanned X-37B space plane later this year. The upstart rocket outfit edged out United Launch Alliance -- a joint venture between Boeing (BA) and Lockheed Martin (LMT) -- that until recently had a monopoly on United States military launches."

The Dragon capsule was the ~12th spacecraft to go to space more than once, and the 8th to reach orbit more than once (after five Space Shuttle orbiters and two X-37B).
NASA considers Dragon missions with a used booster as well. And we can probably see reused payload fairings soon. Then just the second stage is missing. We'll see what they try with the FH maiden flight.

Especially if they get the contract.

They seem to collect US government agencies. NASA (as Dragon customer), NOAA (DSCOVR), NRO (weird ISS-approaching military satellite), Air Force (X-37B, later GPS satellites), what is next?

I can't wait for that one, last I had heard they didn't even have a payload selected. (That would launch a lot of cheese wheels :wink:)

I believe it's a "Done deal"

Now that's interesting o_O

They have the X-37B contract. That's not what I meant.
SpaceX loves competition if that means they get the contract. I'm not sure how happy they are if others get contracts they wanted to get.SpaceX said they try to do something recovery-like with the second stage for the FH maiden flight. I don't expect a full recovery, but if they don't plan at least surviving atmospheric entry I don't understand the announcement.

SpaceX is preparing to launch the second reused booster. Static fire is scheduled for tomorrow, the launch window is Saturday 18:10-20:10 UTC (4 days, 4-6 hours and 20 minutes after this post).
