Fourteen months since its triumphant maiden voyage, the 27 engines of SpaceX’s mighty Falcon Heavy came to life again today (April 5) for a standard launch practice countdown (dress rehearsal) and Static Test Fire, which now paves way for the beast to soar again as soon as April 9, as it takes flight with its first commercial client.

NASA’s Parker Solar Probe (PSP) made its second close approach of the Sun yesterday – the closest that any spacecraft has ever flown past any star.

PSP passed through the outermost layers of the Sun’s atmosphere, the corona, at 213,000 mph, coming within 15 million miles of the Sun itself. Closest approach, called perihelion, occurred at 6:40 p.m. EDT. PSP began this phase of the mission back on March 30, 2019, and it will last until April 10.

'To Finish the Paint Job': Remembering Pad 39B, 50 Years After First Rollout

For five decades, Pad 39B at the Kennedy Space Center (KSC) has served as the starting-point for some of the most pivotal missions in U.S. spaceflight history—from the launches of three Skylab crews and the astronauts of Apollo-Soyuz to more than 50 Space Shuttle flights and the first (and last) flight of the ill-fated Ares I-X—and now stands impatiently primed for the inaugural voyage of the Space Launch System (SLS), sometime after June 2020.

Fifty years ago, this spring, eleven millions pounds-worth (almost 5 million kilograms) of Saturn V booster rolled-out to the pad to become 39B’s first client. Apollo 10 would fly two months later, marking the first time that the new pad would be used to send humans to the Moon. That first rollout, all those years ago, would open the floodgates to a total of 59 launches from the Home Planet, including some of the most pivotal flights of exploration in NASA’s history.

'Full Power for Full Science': Remembering STS-119, Ten Years On

Ten years ago, this month, the crew of shuttle Discovery roared to orbit and achieved—in the words of Kennedy Space Center (KSC) launch commentator Candrea Thomas—“full power for full science” aboard the International Space Station (ISS), by delivering the fourth and final set of U.S.-built solar arrays, batteries and radiators to the sprawling orbital outpost. During their 13 days in space, STS-119 Commander Lee “Bru” Archambault and his crew supported extensive robotics, three sessions of Extravehicular Activity (EVA) and rotated long-duration crew members aboard the ISS, bringing NASA veteran Sandy Magnus home after four months and dropping off Koichi Wakata to become the first Japanese astronaut to fly a long-duration space station mission.

Engineers Conduct Successful First Tests of Mars 2020 Rover

The landing of the Mars 2020 rover on Feb. 18, 2021 may still be almost two years away, but NASA’s newest Mars rover has already “touched down” a couple times in successful test simulations. The tests, with many more to come, will prepare engineers for the actual landing day, which like any Mars rover or lander mission, will be brought with anxiety and suspense as the spacecraft begins its descent through the thin atmosphere.

OSIRIS-REx Finds Plumes and Other Surprises on Asteroid Bennu

Close-up observations of the near-Earth asteroid Bennu have revealed many surprises, NASA announced today during the 50th Lunar and Planetary Conference in Houston. These include particle plumes and a much more rugged surface than had been anticipated.

Remembering Shuttle Discovery's STS-29 Mission, 30 Years On

Flying in space, remembered astronaut John Blaha—who made the first of his five missions, 30 years ago, this month—vanished in the flicker of an eye. On 13 March 1989, Blaha and his four crewmates launched aboard shuttle Discovery on the relatively “vanilla” STS-29 flight to deliver a major NASA communications satellite into space. Seated in the pilot’s seat, alongside future Johnson Space Center (JSC) Director Mike Coats, Blaha was joined by Mission Specialists Bob Springer, Jim Buchli and Jim Bagian. Most of the crew had been recycled from a pre-Challenger assignment to a flight which might have seen the first citizens of Indonesia and the UK to travel into space.

Dedicated to the memory of a former electrical installations lead for the Delta IV Program—30-year aerospace industry veteran Kurt Huschle—the second-to-last “single-stick” United Launch Alliance (ULA) Delta IV booster roared smoothly to orbit this evening (Friday, 15 March), laden with a critical military communications asset to support U.S. and allied warfighters across the globe.

New Crew Launched Aboard Soyuz MS-12, En-Route to Space Station

Two U.S. astronauts rode into orbit, shoulder-to-shoulder with a Russian commander earlier today, when Soyuz MS-12 speared smoothly aloft from Site 1/5—the historic “Gagarin’s Start”—at Baikonur Cosmodrome in Kazakhstan. NASA flyers Nick Hague and Christina Koch were joined by seasoned cosmonaut Alexei Ovchinin for the on-time liftoff and are now embarking on a six-hour and four-orbit “fast rendezvous” to reach the International Space Station (ISS).

By a strange quirk of coincidence, today (3/14) happens to be “Pi Day”, and the mission of Ovchinin, Hague and Koch set off at 3:14 p.m. EDT Thursday (12:14 a.m. local time Friday). “Liftoff on #PiDay,” tweeted Hague in the hours before launch. “An engineer’s dream come true. Next stop, @Space_Station.” The trio are targeted to dock at the station’s Earth-facing (or “nadir”) Rassvet module at 9:07 p.m. EDT.
