When will the Cosmos 1 solar sail spacecraft be launched?

AI Thread Summary
The Cosmos 1 solar sail spacecraft is set to launch between March and April 2005, utilizing sunlight pressure for propulsion. This mission follows a failed prototype launch in 2001 due to insufficient thrust. Cosmos 1 aims to achieve a nearly polar orbit over 500 miles high and will operate for approximately one month. Observers expect the spacecraft's large 100-foot diameter sail to be more visible than typical satellites. The community is eager for updates on when to watch for its appearance in the sky.

A solar sail spacecraft [Cosmos 1] designed to be propelled by the pressure of sunlight will be launched early next year [March - April]
...
A prototype of the society's sail was launched by Russia in 2001 but the rocket did not develop enough thrust and the spacecraft failed to separate from the booster.

Cosmos 1 is designed to go into a nearly polar orbit more than 500 miles high and operate for a month.

That's good news, Phobos. Glad you spotted it. It says that the windmill looking thing will be visible. I sometimes see satellites an hour or two after sunset---they'v always been polar orbit---going roughly north or south. and they look like slowly moving stars

I have the impression that this (because 100? foot diameter) should be
more noticeable. Hope someone at PF will tell us when to be on the lookout.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
