Reply to Three different meteorites in three days -- Feb 13th France, 14th Italy, 15th Texas. by yadavhimanshu961

In mid-February 2023, three different meteorites fell and were recovered within just three days in France, Italy, and Texas. The left image shows the meteorite that fell in France on Feb 13th at 2:59 UTC, the middle image shows the meteorite that fell in Texas on Feb 15th at 23:22 UTC, and the right image shows the meteorite that fell in Italy on Feb 14th at 18:59 UTC. The American Meteor Society reports that all three meteorites have been successfully recovered and will be analyzed to learn more about their origins and composition.

Edit: Here are the details about each of the three meteorites

  1. France (Feb 13th at 2:59 UTC): The first of the three meteorites fell in southwestern France, near the town of Tarbes. The fireball created by the meteor was seen by many witnesses and was captured on video. The meteorite itself weighed around 1.1 kg (2.4 lbs) and was found by a farmer in a field. Preliminary analysis of the meteorite revealed that it is a chondrite, a type of stony meteorite that is one of the most common types to fall to Earth.

  2. Italy (Feb 14th at 18:59 UTC): The second meteorite fell in northern Italy, near the town of Varese. The fireball created by the meteor was seen by many witnesses and was also captured on video. The meteorite itself weighed around 120 grams (4.2 oz) and was found by a local resident. Preliminary analysis of the meteorite suggests that it is a carbonaceous chondrite, a type of stony meteorite that is rare and is known to contain organic compounds.

  3. Texas (Feb 15th at 23:22 UTC): The third meteorite fell in north-central Texas, near the town of Denton. The fireball created by the meteor was seen by many witnesses and was also captured on video. The meteorite itself weighed around 300 grams (10.6 oz) and was found by a local resident. Preliminary analysis of the meteorite indicates that it is an ordinary chondrite.

There is absolutely no evidence whatsoever of your assertion that "Putin" will screw with the space program and in fact there is plenty of evidence to support the opposite conclusion.

If anyone has threatened the space program over deteriorating relations earthside, it's been the Americans. This is yet more bullshit projection of American sins onto the Russians.

Reply to The Paravulcoon - a proposed recovery system for the Saturn rocket, using a hot air balloon to safely land the first stage after use by Watchung

The Paravulcoon was one of a multitude of proposed systems to permit recovery of Saturn boosters for reuse, and among the more delightfully eccentric. The scheme seems simple enough - the envelope emerges as a drogue chute, is rammed full of air, and then propane burners heat the air. After this, a controlled descent occurs. If you're especially bold, one can even use helicopters to tow the balloon to a favorable landing zone.

Scale testing of the system was done by the firm Raven, and proposals for use with the Saturn 1 and Saturn V were floated, but in the end nothing came of the project.
