A SpaceX Falcon 9 booster blasted off from Vandenberg Air Force Base on Tuesday afternoon and successfully orbited seven satellites.
There were five Iridium-NEXT communications satellites aboard. These were the 51st through 56th Iridium-NEXT spacecraft orbited by Falcon 9 boosters.
A pair of Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) satellites were also onboard. The spacecraft will measure changes in how mass is redistributed within and among Earth’s atmosphere, oceans, land and ice sheets, as well as within Earth itself.
The mission is a join collaboration of NASA and the German Research Centre for Geosciences (GFZ). GFZ reports receiving signals from both GRACE-FO satellites.
A German-American science mission scheduled to launch this week is running nine months behind schedule due to issues with launch vehicles. However, the delays turned out to be a blessing in disguise for the project, according to a Government Accountability Office (GAO) assessment.
The twin Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) satellites are set to launch on Tuesday at 12:47:58 p.m. PDT (3:47:58 p.m. EDT; 1947:58 GMT) aboard a SpaceX Falcon 9 booster from Vandenberg Air Force Base in California. The launch will be webcast at www.nasa.gov and www.spacex.com.
There are a dozen orbital launches planned around the world through the end of June.
China will lead off on Sunday as it launches its Chang’e-4 lunar relay satellite from Xichang. A lunar lander and rover targeted for the far side of the moon is scheduled for launch at the end of the year.
Orbital ATK will follow with the launch of a Cygnus resupply ship bound for the International Space Station (ISS) on Monday from Wallops Island. On Tuesday, SpaceX is scheduled to launch 5 Iridium Next satellites and a pair of scientific spacecraft for NASA.
Other notable missions scheduled through June include a Soyuz crew mission and a SpaceX Dragon resupply flight. Rocket Lab is probably going to launch the first commercial flight of its Electron booster from New Zealand. However, the company has not published a launch window for the flight.
The current global schedule is below. Be sure to check Space Flight Now’s launch schedule for updates.
When on May 29, 2014, Elon Musk unveiled the Dragon 2 spacecraft at a gala ceremony at SpaceX headquarters in Hawthorne, Calif., the future of American human spaceflight seemed assured and tantalizingly close.
By 2017, the new spacecraft would begin making crewed flights to the International Space Station, restoring a capability that had ended with the last space shuttle mission in 2011. NASA’s dependence on Russian Soyuz spacecraft would come to an end.
Four years after its unveiling, Dragon 2 is still months away from making an automated flight test to the space station. A test flight with astronauts aboard might not occur until next year. The Government Accountability Office believes additional delays could push certification of the spacecraft to carry NASA astronauts on a commercial basis to December 2019. (Certification of Boeing’s crew vehicle might not occur until February 2020).
It’s good to keep all this in mind as Musk prepares to unveil his latest transportation plan this evening. At 7 p.m. PDT, Musk will hold a town-hall style meeting in Los Angeles to discuss plans by The Boring Company for tunneling under the city. The event will be webcast at https://www.boringcompany.com/.
Musk might have given a preview of the session on Twitter this week when he made a connection between his tunneling work and the mega rocket/spaceship that he is designing to render Dragon 2 and its Falcon 9 booster obsolete.
Boring Company Hyperloop will take you from city center under ground & ocean to spaceport in 10 to 15 mins https://t.co/VhpfhgdXSd
The spaceport in question is apparently the offshore platform where passengers will board the Big Falcon Rocket (BFR), which Musk says will be capable of going anywhere in the world in about 30 minutes. The rocket is also being designed to launch satellites and transport people and cargo to the moon and Mars.
It sounds as ambitious as anything Musk has attempted to date. If the past is any guide, his estimates on cost and schedules will be extremely optimistic.
Elon Musk had a teleconference today concerning the Falcon 9 Block 5 launch vehicle prior to the planned first flight of the upgraded booster. The launch, which would have orbited the Bangabandhu 1 communications satellite for Bangladesh, was scrubbed for an undisclosed technical reason. SpaceX plans to try again on Friday at 4:14 p.m. EDT.
Below are notes from Musk’s teleconference about the upgraded booster and SpaceX’s future plans. (more…)
Update: The launch was scrubbed for an undisclosed technical reason. SpaceX plans to try again on Friday at 4:14 p.m. EDT. Your local time may vary.
Elon Musk’s SpaceX will mark a major milestone for reusable rockets today with the launch of the upgraded Falcon 9 Block 5 booster.
The rocket is set to launch the Bangabandhu communications satellite for Bangladesh from NASA’s Kennedy Space Center in Florida. The launch window runs from 4:12-6:22 p.m. EDT (2012-2222 GMT). SpaceX will webcast the mission at www.spacex.com.
A SpaceX Falcon 9 rocket successfully launched NASA’s Transiting Exoplanet Survey Satellite (TESS) on Wednesday evening. The spacecraft successfully separated from the booster’s second stage about 50 minutes after it was launched from the Cape Canaveral Air Force Station in Florida.
TESS will use four cameras to search 85 percent of the sky for exoplanets orbiting other stars. The mission is a follow-on to the Kepler Space Telescope, which is completing a 9-year mission to survey the other 15 percent of the sky.
The on time launch occurred at 6:51 p.m. EDT. NASA reports the spacecraft’s solar arrays deployed on schedule, providing the satellite with power.
Falcon 9’s first stage successfully landed on a drone ship in the Atlantic Ocean.
MCLEAN, Va., April 09, 2018 (Iridium PR) — Iridium Communications Inc. (NASDAQ:IRDM) announced today that the Iridium-6/GRACE-FO rideshare mission, the sixth Iridium® NEXT launch overall, has been targeted for launch by SpaceX from Vandenberg Air Force Base (VAFB) in California for May 19, 2018 at approximately 1:03 PM PDT (20:03 UTC). An exact instantaneous launch window time will be available closer to launch.
The Wall Street Journal has an update into the failed launch of the classified Zuma payload in January. The spacecraft was launched aboard a SpaceX Falcon 9 booster.
Government and industry experts have tentatively concluded that engineering and testing errors by Northrop Grumman Corp. caused a U.S. spy satellite to plummet into the ocean shortly after a January launch, according to people familiar with the details.
…two separate teams of federal and industry investigators have pinpointed reasons for the high-profile loss to problems with a Northrop-modified part—called a payload adapter — that failed to operate properly in space….
The device, purchased from a subcontractor, was significantly modified and then successfully tested three times on the ground by Northrop Grumman, according to one person familiar with the process. But upon reaching orbit, this person said, the adapter didn’t uncouple the satellite from the rocket in zero-gravity conditions.
Sensors on board failed to immediately report what happened, this person said, so officials tracking the launch weren’t aware of the major malfunction until the satellite was dragged back into the atmosphere by the returning second stage. The satellite ultimately broke free but by then had dropped to an altitude that was too low for a rescue.
CAPE CANAVERAL AIR FORCE STATION, Fla. (NASA PR) — Astronauts aboard the International Space Station soon will receive a delivery of experiments dealing with how the human body, plants and materials behave in space following the 4:30 p.m. EDT launch Monday of a SpaceX commercial resupply mission.
A SpaceX Dragon lifted off on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida with more than 5,800 pounds of research investigations and equipment, cargo and supplies that will support dozens of the more than 250 investigations aboard the space station.
The world’s launch providers have been extremely busy in the first quarter of 2018, with 31 orbital launches thus far. This is more than one third of the 90 launches conducted last year.
China leads the pack with 10 successful launches. The United States is close behind with a total of nine launches with one failure. The tenth American launch is scheduled for Monday afternoon from Florida.
