X-37 dodges Hurricane Irma aboard a Falcon 9

Today was the scheduled liftoff day for the fifth X-37 mission (OTV-5), and the first aboard a Falcon 9.  (X-37 was designed from the start to be compatible with almost any launch vehicle, including the Space Shuttle, but its first four launches were all aboard the Atlas V.)  As a bonus, since SpaceX is still unable to use their original Florida launchpad, Cape Canaveral Air Station’s SLC-40, this launch used the pad they’re adapting for Falcon Heavy, Kennedy Space Center’s venerable LC-39A.  So LC-39A got to launch another spaceplane after all.  😉  (LC-39A’s last spaceplane launch was STS-135, the final flight of the Space Shuttle program, just over six years ago.)

Coverage of the ascent stops with first stage separation, as normal for classified flights*, but since this was Falcon 9, we got to see coverage of the first stage continue all the way to touchdown back at the Cape.  Now, SpaceX gets to scramble to safe it and stash it safely in a hangar in advance of Hurricane Irma.

*X-37 is not a classified spacecraft, but its missions are generally classified.  This one does carry one unclassified payload, the Advanced Structurally Embedded Thermal Spreader, for the Air Force Research Laboratory.  It will “test experimental electronics and oscillating heat pipe technologies in the long duration space environment”.  Satellites already use heat pipe technology to draw waste heat away from sensitive electronic components (since obviously fans don’t work for cooling a spacecraft computer), but this new technology will be lighter and cheaper.  All the other payloads, as well as their quantity and the target orbit and any planned maneuvers, remain classified.  But they are probably also experimental technologies, since X-37 offers a unique opportunity to test equipment for a long duration in space and recover it for extensive engineering analysis afterwards.

Falcon 9 lifts the second batch of Iridium Next spacecraft

Yesterday, less than 48 hours after the last Falcon 9 launch (from KSC’s LC-39A), a second Falcon 9 blasted off.  This one launched from Vandenberg AFB’s SLC-4 and delivered the next ten Iridium Next satellites.  Once enough Iridum Next spacecraft are delivered to orbit, they will begin to replace the famous initial constellation, which is nearing the end of its service life.  Alas, the new spacecraft are much smaller than the original Iridiums and will not wow spotters with bright flares with each pass.

The Falcon 9 for this flight is a full thrust Falcon 9 equipped with a new, all-titanium set of grid fins.  They’re heavier than the older ones, but can handle larger loads and provide more control authority.  This will be critical when the Falcon Heavy’s three cores attempt to return later this year.

This spacecraft’s first stage was successfully recovered by the drone ship Just Read The Instructions, and will eventually be reflown.

Bulgaria enters the space community, as the second reused Falcon 9 flies!

SpaceX completed another successful launch today — and the first droneship recovery of a reused booster — placing BulgariaSat1 into geosynchronous transfer orbit.  It was the hottest and hardest return yet, and not quite squarely on the droneship (“Of Course I Still Love You”), but it was successful.

SpaceX isn’t quite done yet — they’re planning another launch on Sunday with the second set of ten Iridium Next satellites from Vandenberg AFB.  It’s a busy launch weekend; I’ll have more rocket launch videos tomorrow.  😉

SpaceX has reflown a booster!

The first reflown Falcon 9 first stage core has completed its second mission, and been recovered successfully on a barge at sea.  They also apparently recovered half of the payload fairing, which I didn’t know they were even thinking about attempting.  The upper stage went on to deliver SES-10 to the correct geosynchronous transfer orbit.

Space news catchup! Vega, Blue Origin, GOES-16’s lightning mapper, and more!

It’s been really busy lately, so I haven’t has as much time to post as I’d like.  So today I will make up for it with a bunch of space news updates!

First off, a rocket launch is always fun.  Arianespace’s Vega launcher placed the Sentinel 2B environmental monitoring satellite into orbit from Kourou, French Guiana:

Meanwhile, GOES-16 continues its commissioning phase.  As part of that, it has returned its first view of lightning from 22,000 miles away, a demonstration of its incredible capacity at this range.  The green lines represent the coast of Texas.  The lightning is all in real time, and is overlaid over an image taken at the same time by GOES-16’s revolutionary Advanced Baseline Imager.

This full-disk image was created from data from the same instrument, and shows total lightning energy recorded over a one-hour period (an hour which included the image above; that really bright spot in this image is the same storm system over Texas):

And then let’s go back to rockets!  Blue Origin unveiled their New Glenn rocket today with an animation depicting its flight profile.  It is definitely similar to the strategy SpaceX is using, but one difference is that the engine, BE-4, will also by flying on another rocket, ULA’s Vulcan.  Another difference is the strakes.  It looks quite lovely, and I hope we’ll get to see it fly soon.  They do already have a customer for it: the first flight customer will be Eutelsat.

And then, how about some good news on the political front?  Cutting NASA has long been a bipartisan pasttime, but the tides seem to be changing.  A strong bipartisan majority in the House of Representatives voted to pass the NASA Authorization Bill, the first time they’ve managed to do so despite annual attempts in the past six years.  (NASA has been operating under continuing resolutions instead.)  This bill budgets $19.5 billion for NASA in 2017.  Of course, now we have to see what actually gets appropriated; that’s a separate battle, and will start with the White House federal budget request.  So cross your fingers, space geeks!

Falcon 9 arrives in Los Angeles

The Falcon 9 first stage that placed the first flight of Iridium Next spacecraft into orbit has returned to land, coming ashore on its drone barge “Just Read The Instructions” at the Port of Los Angeles.

Meanwhile, the first reflown booster has been announced: as rumored, the customers is SES, and in fact the first flown booster will carry their SES 10 payload in just a month’s time.  SpaceX has a very busy plate ahead of them, catching up from their hiatus, and so Falcon 9 will actually manage to fly three more times before the SES 10 mission.

Falcon 9 has returned to flight!

After the shocking loss of the last Falcon 9, the rocket roared well and truly back into business today.  They had been slightly delayed by the much needed rains that have come to California, but today the weather was suitable and launch occurred on time and on target, with a successful barge recovery at sea of the first stage – the first from Vandenberg.  The Jason-3 launch a year ago was the first attempt to recover a Falcon 9 in the Pacific; it successfully soft-landed, but one of the landing legs failed to lock allowing it to fall over and explode.  This one was flawless, and the barge will return to shore in the next couple of days — I believe to San Diego, since that’s where SpaceX recovers their Dragons.

The payload is the first flight of the Iridium NEXT constellation, which uses a brand-new multi-satellite deployment system that appears to have worked flawlessly, deploying all ten spacecraft correctly into their high inclination orbit.
