Russia launches first Moon mission in nearly 50 years

Russia launched its first probe to the Moon in almost 50 years on Friday, a mission designed to give fresh impetus to its space sector, which has been struggling for years and become isolated by the conflict in Ukraine.
The launch of the Luna-25 probe is Moscow's first lunar mission since 1976, when the USSR was a pioneer in the conquest of space.

Virgin Galactic launched its first tourist passengers into the weightlessness of space Thursday, the culmination of a nearly two-decade commercial pursuit, the company said.
The three passengers - Jon Goodwin, Keisha Schahaff, and her teenage daughter Anastatia Mayers - floated gravity-free through the Virgin spacecraft about 45 minutes after taking off.

Watch NASA engineers put a Mars lander's legs to the test
Thursday, 10 August 2023 18:24 Write a comment
Sturdy legs are needed to absorb the impact of the heaviest spacecraft to ever touch down on the Red Planet.
NASA's Perseverance rover continues to rack up tubes filled with rock core samples for the planned Mars Sample Return campaign. The joint effort by NASA and ESA (European Space Agency) seeks to bring scientifically selected samples back from Mars to be studied on Earth with lab equipment far more complex than could be brought to the Red Planet. Engineers are busy designing the Sample Retrieval Lander that would help bring those samples to Earth. As part of that effort, they've been testing prototypes of the lander's legs and footpads at NASA's Jet Propulsion Laboratory in Southern California.

Course correction keeps Parker Solar Probe on track for Venus flyby
Thursday, 10 August 2023 14:10 Write a comment
NASA's Parker Solar Probe executed a short maneuver on Aug. 3, 2023, that kept the spacecraft on track to hit the aim point for the mission's sixth Venus flyby on Monday, Aug. 21, 2023.
Operating on preprogrammed commands from mission control at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, Parker fired its small thrusters for 4.5 seconds, enough to adjust its trajectory by 77 miles and speed up—by 1.4 seconds—its closest approach to Venus. The precise timing and position are critical to that flyby, the sixth of seven approaches in which Parker uses the planet's gravity to tighten its orbit around the sun.
"Parker's velocity is about 8.7 miles per second, so in terms of changing the spacecraft's speed and direction, this trajectory correction maneuver may seem insignificant," said Yanping Guo, mission design and navigation manager at APL.
