MS-09 launched on June 8th and has a guaranteed lifespan to December 5th (180 days docked, though that's stretchable). MS-11 is planned to launch December 20th.

I think 200 or so days is the upper bound. Everything hinges on the decision to launch MS-11 whether manned or unmanned. I believe they also need Hague's maintenance skills for some ISS work.

The livestream of the launch was uploaded onto youtube; it seems there's a complete booster failure - ignoring the simulated telemetry shown, and listening to the event it sounds as if the first stage just quit.  Possibly something with the escape tower; when it detaches it's a hell of a violent jolt that you can see on the crew camera.  It was very soon after that that the emergency was declared, and the crew is talking about freefall almost immediately, yet according to the simulation it should still be running on the first stage engine.

Liftoff is at 24:25, first emergency call is T+02:45 at 27:10 video timehack (11:42:17 local time).  "The failure of the booster" could be anything.

Hopefully they will be able to go through the data figure out what went wrong with the booster.

ISS going need something sent up there. From what i read, at least one of the commercial spacecraft is closer to being ready but the paper work is what bigger issue get through.

ISS won't last long if the crew leaves.  :(

NASA can fly it remotely for a time and the orbit is near the high end of its range, so less atmospheric drag, but yes. There is a limited time due to maintenance.

Neither of the CCP spacecraft are going to be ready in anything like the time required. Soyuz will have to become spaceworthy again first. I would be reasonably confident about that given the program's history, but that drill-hole in the current spacecraft, while not a factor in getting the crew home as the affected wall is the orbital module, indicates possible QC issues.

Given the relations between ESA and the Chinese it's not really that farfetched to mount something KURS-compatible on Shenzhou 12. I mean, Germany and Italy already have two astronauts that have taken part in taikonaut training for Shenzhou, have been learning Chinese for five years and that in one case has already been on ISS (the other one is supposed to go up in 2020). And the capsule's been ready for a while. Just gotta pull the deployment schedule forward a bit.

Well, if NASA wasn't in the way.

Scott Manley is going for a failure of the oxygen vent that starts the strap on booster rotating away from the rocket.

This Mercury Satellite BepiColombo (Cowboy Bebop?) does a camera test, of taking pictures of self.



Another thing i just read is amusing...but bit strange is Nasa gave temporary named some constellations....oddly with pop culture names. Like the Tardis, Starship Enterprise, Hulk to name a few.  It was done with the Fermi Gamma-ray Space Telescope.

BepiColombo (Cowboy Bebop?)
The spacecraft is named for Giuseppe "Bepi" Colombo, an engineer and mathematician who first implemented gravity-assist in space missions - as part of mission planning for Mariner 10's spindown to Mercury in 1973.

One of very few people who lived during the space age - he died in '84 - to have the honor of having a mission named after them. Only other ones i can think of were Subrahmanyan Chandrasekhar, Lyman Spitzer, James van Allen and Eugene Parker, and for planned ones of course James E. Webb (note: all of them NASA spacecraft...).

Planck, Fermi and Hubble for other 20th-century people with missions named after them all died before Sputnik.

does a camera test, of taking pictures of self.
MTM - "Mercury Transfer Module", the carrier spacecraft - only carries these three cameras, and only for the purpose of self-monitoring. Left picture is M-CAM1 which observes deployment of MTM's solar rays; M-CAM2 (center) and M-CAM3 (right) instead observe the satellite carried forward of MTM (MPO), precisely its medium- and high-gain antennas respectively - MTM itself doesn't carry communications gear and uses MPO for that during interplanetary transfer.

The monitoring cameras will be used during all flybys - at Earth (Apr'20), Venus (Oct'20 and Aug'21) and Mercury (Oct'21, Jun'22, Jun'23, Sep'24, Dec'24, Jan'25) - for snapshots during the cruise phase.

MPO's instruments for protection are mounted on the side that faces MTM, and thus are not usable until MTM deploys her at Mercury. Forward of MPO the second satellite MMO is stowed during cruise.

P.S.:



From bottom:
- MTM : propulsion unit
- MPO : separating satellite (ESA)
- MOSIF : protective structure for MMO
- MMO : separating satellite (JAXA; nickname "Mio")

MTM basically carries it all to shortly before Mercury and releases the stack there before orbital insertion. MPO will first detach MMO, then ditch MOSIF and then move into its own orbit.

MMO, once no longer in MOSIF, will spin up to 15 rpm for heat management and enter a high elliptic orbit around Mercury.
MPO, will go into a medium-altitude polar orbit around Mercury. Heat management is done through that huge radiator at the front in the above picture.
MOSIF stays attached to MPO for two more maneuvers after MMO is deployed, and is then released into "a safe direction" - meaning probably towards the sun.

More news from our recent speedy visitor 'Oumuamua.  You remember the part where it's accelerating out of the solar system?  Where it's not just on a Keplerian orbit but is actually speeding up more than it should be?  A couple astrophysicists at Cambridge point out it's got the flight characteristics of either a lightweight comet or a lightsail...and it's never shown any sign of a coma, tail, or outgassing of any volatiles at all.

https://arxiv.org/abs/1810.11490v2

'Oumuamua's next stop is Pegasus...noteworthy in that 51 Pegasi was the first Sun-like star discovered to have an exoplanet companion.  Nah, just coincidence.

The Parker Probe has sent dozy of a picture of what's like to be at the edge of the Sun. I got this report from spacedaily.


The image is from November 8th,  this is the coronal streamer, seen over the east limb of the Sun.

Love that Parker probe.  The science and speed combo is fantastic.  Not only do we get a new view of the sun, we get an ongoing test of the extreme limits of out technology.   Boundaries are set up to be surpassed with each orbit of the Parker.

The second of the Minerva-II-1 hoppers stopped moving about a week ago, exceeding their original planned life span of a few days by several months, hopping some 300 meters distance along it and taking over 200 photos. The first one stopped moving after ten days and 40 photos. Both rovers are still in active communications with Hayabusa 2.

The hopper technology is figuring huge in future proposed missions.  Mechanical and propeler driven (where atmospheres are present) hopper ideas are now the idea dejour, especially for missions to moons and yes, future asteroid missions.

What direction is New Horizons going vs where newly discovered 2018 VG18 (aka Farout) Dwarf Planet?  I know she low on fuel, but does anyone think it's in right position to attempt top steer that direction?  I know it's remote chance of it if going direction, but i wanted to ask people's options.

I found XKCD comic amusing addition to the rocket launch news weekly report put out by Aris Technica.

Since next year posed to have a lot interesting launches next year.
SpaceX going be launching two Heavy Falcon launches, the US Air Force maybe purchasing some Falcon 9s for their own use.  Delta Heavy going to be hopefully launching soon, with Dream Chaser mini-shuttle cargo variant finally getting off the ground next year to say least.

This image is courtesy of Space.com and the European Space Agency via its Mars Express orbiter.  A frozen lake in Korolev crater, near the martian north pole.  It is pressumed to be mostly water ice. 

Regardless of what's in the crater, this is a beautiful shot.

Its awesome.  My only thing about Mars photos that there been this under tone that NASA has to colorize pictures or something.  Is the picture actual picture with colors that human eye would see or does it look different because how light and atmosphere change what we see?

That's a good question.  It apears to be natural colors, but I could be wrong.    In the original size picture, the resolution is incredible; you can see the fog over the colder surface below.   I tried to attach this so people can get the original size but it's the wrong format and wouldn't post.

HRSC takes four pictures with parallel mounted cameras with blue, green, red and infrared spectral filters (plus three additional with b/w canted cameras for 3D effects). These are later processed into a single color picture, in this case they additionally created a mosaic out of five spot sessions.

The colors are corrected for lighting and atmospheric effects using another spectroscopic instrument on the satellite as well as pictures being taken of Earth with another HRSC model for comparison. This mostly reduces the red and increases the blue compared to how Mars Express sees it from orbit, in order to emulate a "as its really colored" view. There's about a dozen different color correction profiles for various latitudes and ground composition though and e.g. the ice is likely differently corrected than the ground around it.

The original stitched-up picture (21 MB TIF, 4K resolution) is straight top-down. For the oblique view shown above the color picture is overlaid as a texture onto a digital terrain model and canted.

Looks like New Horizons is on course for it's next encounter, with 2014 MU69, Ultima Thule.



Reported here on Vox.


I hope they may have enough life left in the Probe go visit something else before it's off in outreaches.

Closest approach is, IIRC, about 2200 miles so as long as everything is still working it'll get significantly better detail than the 7300 mile altitude on Pluto.
