**Progress 1** ([Russian](/source/Russian_language): *Прогресс 1*), was a [Soviet](/source/Soviet_Union) unmanned [Progress](/source/Progress_(spacecraft)) cargo spacecraft which was launched in 1978 to resupply the [Salyut 6](/source/Salyut_6) space station. It was the maiden flight of the Progress spacecraft, and used the [Progress 7K-TG](/source/Progress_7K-TG) configuration. It carried supplies for the [EO-1](/source/Salyut_6_EO-1) crew aboard Salyut 6, which consisted of Soviet cosmonauts [Yuri Romanenko](/source/Yuri_Romanenko) and [Georgy Grechko](/source/Georgy_Grechko). The cargo carried by Progress 1 also included equipment for conducting scientific research, and fuel for adjusting the station's orbit and performing manoeuvres.

## Spacecraft

Main article: [Progress 7K-TG](/source/Progress_7K-TG)

Progress 1 was a Progress 7K-TG spacecraft. The first of forty three to be launched,[1] it had the [serial number](/source/Serial_number) 102.[2] The Progress 7K-TG spacecraft was the first generation [Progress](/source/Progress_(spacecraft)), derived from the [Soyuz 7K-T](/source/Soyuz_7K-T) and intended for unmanned logistics missions to space stations in support of the [Salyut programme](/source/Salyut_program).[3] The spacecraft were also used on some missions to adjust the orbit of the space station.[4]

The Progress spacecraft had a dry mass of 6,520 kilograms (14,370 lb), which increased to around 7,020 kilograms (15,480 lb) when fully fuelled. It measured 7.48 metres (24.5 ft) in length, and 2.72 metres (8 ft 11 in) in diameter. Each spacecraft could accommodate up to 2,500 kilograms (5,500 lb) of payload, consisting of dry cargo and propellant. The spacecraft were powered by chemical batteries, and could operate in free flight for up to three days, remaining docked to the station for up to thirty.[3][4]

## Launch and docking

Progress 1 was launched at 08:24:40 UTC on 20 January 1978, atop a [Soyuz-U](/source/Soyuz-U) 11A511U carrier rocket flying from [Site 31/6](/source/Baikonur_Cosmodrome_Site_31) at the [Baikonur Cosmodrome](/source/Baikonur_Cosmodrome), [USSR](/source/USSR). The rocket that launched it had the [serial number](/source/Serial_number) E15000-075.[5] Following launch, Progress 1 was given the COSPAR designation 1978-008A, whilst [NORAD](/source/NORAD) assigned it the [Satellite Catalog Number](/source/Satellite_Catalog_Number) 10603.[6]

Following launch, Progress 1 began two days of free flight. It subsequently docked with the aft port of the Salyut 6 space station at 10:12:14 UTC on 22 January 1978.[3][7] When the Progress spacecraft docked, the station's other docking port was occupied by the [Soyuz 27](/source/Soyuz_27) spacecraft.[8]

## Mission

Progress 1 was the first of twelve Progress spacecraft used to supply the Salyut 6 space station between 1978 and 1981.[6] Its payload of 2,300 kilograms (5,100 lb) consisted of 1,000 kilograms (2,200 lb) of propellant and oxygen,[9] as well as 1,300 kilograms (2,900 lb) of food, replacement parts, scientific instruments, and other supplies.[8] Whilst Progress 1 was docked, the EO-1 crew, consisting of cosmonauts Yuri Romanenko and Georgi Grechko, was aboard the station.[10] Progress 1 demonstrated the capability to refuel a spacecraft on orbit, critical for long-term station operations.[11] Once the cosmonauts had unloaded the cargo delivered by Progress 1, they loaded refuse onto the freighter for disposal.

On 6 February 1978, Progress 1 was catalogued in a [low Earth orbit](/source/Low_Earth_orbit) with a [perigee](/source/Apsis) of 329 kilometres (204 mi) and an [apogee](/source/Apsis) of 348 kilometres (216 mi), [inclined](/source/Orbital_inclination) at 51.66° and with a [period](/source/Orbital_period) of 91.3 minutes.[12] Progress 1 undocked from Salyut 6 at 05:54 UTC on 6 February.[7] It remained in orbit for two more days, finally being deorbited to a destructive [reentry](/source/Atmospheric_re-entry) over the [Pacific Ocean](/source/Pacific_Ocean) at around 02:45 UTC on 8 February 1978.[12][3]
