A problem with another one of the eight prevalves in the Artemis 1 Core Stage for NASA’s Space Launch System (SLS) has postponed a second test-firing to wrap up the Green Run campaign. The SLS Program’s first flight article has been installed in the B-2 Test Stand at the Stennis Space Center in southern Mississippi since January 2020. After a liquid hydrogen prevalve was repaired in […]
After successfully touching down on the Martian surface on February 18, 2021, NASA teams have started the many checkouts required to begin operating the Perseverance rover. The mission touched down within five meters of their landing target (the landing target that was chosen by the terrain relative navigation system, not the pre-planned estimation), and several minutes later sent its first image of the Martian surface back […]
In large part, it is impossible to have escaped notice of a rather large debate swirling in the planetary community around a theorized super-Earth planet in the outer reaches of our solar system, the existence of which could be one possible explanation to several oddities observed in a very dynamic part of our galactic home. So where does current research, distant solar system observations, and searches […]

SpaceX is preparing for their third launch of 2021 and the first of many planned Smallsat Rideshare Program missions, which are designed by the company to give small satellite operators the chance to launch together as a way to reduce cost on regularly scheduled flights to frequently used orbits. The flight, called Transporter-1, which will launch a record number of satellites on the same mission, is […]
It’s one of the greatest mysteries in solar physics. Dubbed the coronal heating problem, the issue arises from the fact that the solar corona, or Sun’s atmosphere, is millions of degrees hotter than the layers directly below it. This goes against modeling that suggests the corona should be far cooler than the layers below it. Numerous theories have been proposed to explain the problem, but a […]

The NASA Exploration Ground Systems (EGS) program at Kennedy Space Center (KSC) in Florida is prepared to continue integration of the vehicle for the Artemis 1 lunar mission, but space agency and contractor management for the EGS, Orion, and Space Launch System (SLS) programs are monitoring the status of hardware elements that will be needed to complete the process for a launch scheduled for November 2021. […]
Most rocket launches culminate with liquid-fueled upper stage engines turning off at exactly the precise millisecond a host of parameters — such as flight path angle, orbital inclination, apogee, and perigee — are all met simultaneously. So then how do solid propellant upper stages like those used on the Antares, Pegasus, and Minotaur fleets from Northrop Grumman perform those same types of mission-precise orbital insertions when […]

Arianespace will use — with Russia’s support — a Soyuz ST-A rocket to launch a joint military and civilian Earth imaging satellite for the United Arab Emirates Armed Forces from the Guiana Space Centre near Kourou, French Guiana. Liftoff of the Falcon Eye 2 satellite is set to occur at 20:33:28 EST on Tuesday, 1 December (01:33:28 UTC on Wednesday, 2 December) to ensure the satellite […]
Eight days after launching from the Wenchang Spacecraft Launch Site in southern China, the nation’s Chang’e 5 mission has landed at Mons Rümker on the Moon to collect approximately 2 kg of material for near-immediate return to Earth. The Chang’e 5 lander began final descent at 09:58 EST (14:58 UTC) with an expected touchdown 15 minutes later at 10:13 EST (15:13 UTC). All broadcasts of the […]
It’s a constant of the universe. Dark matter – a key ingredient for the formation and evolution of galaxies is present in whatever galaxy is observed. That is until NGC 1052-DF2 was discovered – a galaxy missing most of its dark matter. A year later, galaxy NGC 1052-DF4 was discovered 45 million light years from Earth… and it too was missing most of its dark matter. […]
Arianespace is preparing to use — with Russia’s support — a Soyuz ST-A rocket to launch a joint military and civilian Earth imaging satellite for the United Arab Emirates Armed Forces from the Guiana Space Centre near Kourou, French Guiana. The Falcon Eye 2 satellite for the United Arab Emirates has a single-second launch window at 20:33:28 EST on Sunday, 29 November (01:33:28 UTC on Monday, […]
Mitsubishi Heavy Industries of Japan plans to launch an H-IIA rocket on Sunday, 29 November to deploy a top secret communications satellite to support the country’s reconnaissance and scientific programs. Liftoff is scheduled for a two-hour window opening at 16:25 local time (07:25 UTC or 02:25 EST) from the Tanegashima Space Center. The payload The Optical Data Relay Satellite payload aboard this mission will be used […]
NASA Exploration Ground Systems (EGS) and prime test and operations contractor (TOSC) Jacobs started assembling the Artemis 1 vehicle on its Mobile Launcher this week in the Vehicle Assembly Building (VAB) at the Kennedy Space Center (KSC) in Florida. Placement of the two aft assemblies of the Space Launch System (SLS) solid rocket boosters (SRB) on Mobile Launcher-1 (ML-1) in VAB High Bay 3 begins the […]
The Liquid Engines Office for NASA’s Space Launch System (SLS) Program is planning a busy schedule of test campaigns next year in parallel with efforts to complete preparations for the vehicle’s first launch. Existing Aerojet Rocketdyne hydrogen-oxygen engine designs and hardware will be used for the SLS core and upper stages, but both the space agency and the prime contractor for the RS-25 and RL10 engines […]
Following a slightly convoluted engine testing campaign, Starship SN8 is set to finalize its pre-flight requirements with a triple Raptor Static Fire test on Tuesday. Should this test go to plan, the path will be cleared for SN8 to conduct a test flight to 15 km (50,000 ft) as soon as November 30. This three-engine firing is expected to be the final major test ahead of […]
The Chang’e 5 lunar orbiter, lander, and sample collection return vehicle is on its sea-side launch pad at the Wenchang Spacecraft Launch Center in Wenchang, Hainan province, People’s Republic of China. The mission will launch on a Chang Zheng 5 heavy lift rocket, with liftoff expected within a 50 minute launch window that extends from 20:25 to 21:15 UTC (16:25 to 17:15 EST) on 23 November. […]
Just over a day after a SpaceX Falcon 9 rocket carried the American-European Sentinel-6A oceanography satellite into orbit from the U.S. West Coast, SpaceX has returned its focus to the Cape Canaveral Air Force Station in Florida, ahead of the Falcon 9 rocket’s 100th launch. With the Starlink V1.0 L15 mission (or the 16th flight of Starlink), SpaceX’s latest batch of 60 satellites are scheduled to […]
Fresh off their second crewed launch for NASA, SpaceX has temporarily shifted focus on launches to the U.S. West Coast, where a Falcon 9 rocket is waiting to launch the Sentinel-6 Michael Freilich oceanography satellite in cooperation with NASA, the National Oceanic and Atmospheric Administration, the European Space Agency, and various other partners. Launch is scheduled from Space Launch Complex 4 East (SLC-4E) at Vandenberg Air […]
NASA’s Space Launch System (SLS) Program rescheduled the final two tests that will culminate the Core Stage Green Run campaign for December after successfully repairing one of the liquid hydrogen (LH2) prevalves inside the engine section of the stage. The Wet Dress Rehearsal is now targeted for the week of December 7, and if that goes well the Hot-Fire test of the stage could occur two […]
Rocket Lab is preparing to launch its sixth mission of 2020 — a launch which the company calls its “most diverse mission yet,” with 30 satellites onboard and a launch broadcast that will raise money for the Paediatric Intensive Care Unit at Starship children’s hospital. Electron will blast off from LC-1A on New Zealand’s Māhia Peninsula. The launch is targeted for the opening of the window […]
