+Mission: *.1 ++Name: VEGA-1 ++SatZond: Z ++GeoHelBoth: H ++Launch: 84/12/15 --TrajectFile: Y ++ShortDescription: The 17th Russian expedition to Venus + Galley comet encounter ++LongDescription: Russian space zond for Venus exploration; landing a craft, download a bolloon; then free flight to encounter the Galley comet. A couple of zonds, VEGA-1 and VEGA-2 have been launched in a 6-day interval. Main axis of the spacecraft is sunward directed with precision of ~10 degrees. ++Instrument: *.1 +++Name: VFS-VK +++PI: Dr. Vladimir I.

There are three closely placed gas-discharge counters of the SBM-20 series. Data is recorded both from single counters and from coinciding combinations of pulses. Spacecraft memory is used for data storing; time resolution is about twenty minutes. All sensors measure flux intensity continuously. +++Publication: *.1 ++++PublicationRef: V.N.Ishkov, G.Ya.Kolesov, Yu.I.Logachev, A.H.Podorolsky, G.P.Lyubimov, V.I.Tulupov, and E.A.Chuchkov, "A series of solar-proton events from an active region observed on PROZNOZ-10, INTERCOSMOS and BEGA-1,2 in July 1985", Kosmicheskie issledovaniya, 1989, v. 27, N 3, pp.402-406 +++AcknowledgingTo: TASPD SINP MSU +++DataSet: *.1 ++++ID: A1 ++++StartDate: 84/12/22 ++++StopDate: 86/07/08 ++++TimeResolution: 20 minutes ++++ApproxVolume: 850 kB ++++DataSupportContact: Dr. Nickolay N.
