"This impressive scene was photographed when the NASA 747 carrier aircraft and five T-38 aircraft flew over the shuttle Orbiter 101 'Enterprise' while it was parked on the runway at Edwards Air Force Base in Southern California."

Astronauts Joe H. Engle (face down), commander, and Richard H. Truly (face partially obscured by Engle), pilot, are greeted by Rockwell technicians following egress from Enterprise.

"She had just completed a five-minute, 28-second unpowered mission during the second free flight of the Shuttle Approach and Landing Tests (ALT) conducted at the Dryden Flight Research Center."

"The astronauts reported that the use of ailerons after nosewheel touchdown was not as effective in steering the orbiter as predicted, but other than that, the vehicle had performed well in flight. The most serious problem to come along during the flight was not in either of the flight vehicles: the radar at Dryden failed 28 minutes into the captive portion of the flight, and almost caused an abort before it was brought back online."

"Line drawing charts the Galileo spacecraft's launch from low Earth orbit and its three planetary and two asteroid encounters in the course of its gravity-assisted flight to Jupiter. These encounters include Venus (February 1990), two Earth passes (December 1990 and December 1992), and the asteroids Gaspra and Ida in the asteroid belt. Galileo will release a probe and will arrive at Jupiter, 12-07-95."

Perseverance rover discovered potential biosignature

NASA’s Perseverance rover discovered leopard spots on a reddish rock nicknamed “Cheyava Falls” in Mars’ Jezero Crater in July 2024. Scientists think the spots may indicate that, billions of years ago, the chemical reactions in this rock could have supported microbial life; other explanations are being considered.

Launch of Big Joe-1

Big Joe-1 Mercury Atlas launch vehicle lifting off at LC-14, Cape Canaveral, Florida, for a 13 minute suborbital test flight of the Mercury Boilerplate capsule.

Flight plan of Big Joe

"Mission Objective:

Test of ablation heatshield. The nose-cone capsule for Big Joe had no retrorocket package. The inner structure held only a half-sized instrumented pressure vessel instead of a pressurized cabin contoured to the outer configuration. Built in two segments, the lower half by Lewis and the upper by Langley, the main body of the spacecraft replica was fabricated with thin sheets of corrugated Inconel alloy in monocoque construction. This model of the Mercury capsule had more than one hundred thermocouples around the capsule skin to register temperatures inside and under the heatshield, sides and afterbody."

"The Atlas 10-D was programmed to rise, pitch over horizontally to the Atlantic before it reached its 100-mile peak altitude, then pitch down slightly before releasing its corrugated nose cone at a shallow angle barely below the horizontal."

The flight was deemed a success and the second flight (Big Joe 2, Atlas-20D) was cancelled. Its launch vehicle was transferred to the Atlas-Able program.

Astronomers have unveiled a spectacular cosmic scene: WISPIT 2b, a newborn gas giant 5 times the size of Jupiter, actively forming within a multi-ringed protoplanetary disk.

Growing Tail of Interstellar Comet 3I/ATLAS

On 27 August 2025, researchers used the Gemini Multi-Object Spectrograph (GMOS) on Gemini South at Cerro Pachón in Chile to obtain deep, multi-color images of interstellar comet Comet 3I/ATLAS.

Westerlund 1 is the biggest and closest "super" star cluster to Earth. Some of the stars found here shine with the brightness of almost one million Suns! This new image combines X-ray light from Chandra, optical light from Hubble, and infrared light from JWST.

A Titan-Centaur rocket carrying the Viking 1 spacecraft launches from Complex 41 at Cape Canaveral Air Force Station on Aug. 20, 1975. Viking 1 touched down on the red planet on July 20, 1976, becoming the first truly successful landing on Mars. Viking 1 was the first of a pair of complex deep space probes that were designed to reach Mars and to collect evidence on the possibility on life on Mars.
