This is the launch thread for Aditya-L1, both updates and discussion.

We also have the Aditya-L1 Solar Observation Mission mission thread in the Space Science sub-forum.

Aditya - L1 First Indian mission to study the Sun

The Aditya-1 mission was conceived as a 400kg class satellite carrying one payload, the Visible Emission Line Coronagraph (VELC) and was planned to launch in a 800 km low earth orbit.  A Satellite placed in the halo orbit around the Lagrangian point 1 (L1) of the Sun-Earth system has the major advantage of continuously viewing the Sun without any occultation/eclipses.  Therefore, the Aditya-1 mission has now been revised to “Aditya-L1 mission” and will be inserted in a halo orbit around the L1, which is 1.5 million km from the Earth.  The satellite carries additional six payloads with enhanced science scope and objectives.

The project is approved and the satellite will be launched during 2019 – 2020 timeframe by PSLV-XL from Sriharikota.

ISRO has intensified its arrangements to launch Aditya L1 satellite by PSLV-C56 rocket from Sriharikota in January 2023. SHAR Director Armugam Rajarajan revealed this to the media.

Perhaps five Indian orbital launches before the end of the Indian fiscal year March 31, 2023:
[YouTube link]
Oceansat-3: end of November;
The 2nd OneWeb cluster launch: January or February, LVM3 M3;
The 2nd SSLV launch;
GSLV (MkII) NavIC satellite, apparently IRNSS-1J (1st of 5 2nd generation NavIC satellites ordered, which matches the circumstances of 1J);
Perhaps Aditya-L1.

Quote from: Sidharth MP tweet
Chandrayaan-3, we will have this year end or next year beginning..discussions underway about the next #mars mission..now we’re going to the Sun- Aditya-L1 by June-July..mission to asteroid, to Venus are at discussion level as I understand” Umamaheswaran, #isro HSFC Director [Jan 28]

[ISRO Director S Somnath]

Next launches are GSLV, PSLV and LVM-3. Three major missions in next few months.

Aditya-L1 launch NET mid July.  Or NET late July?  How quickly in succession can two overlapping launch campaigns, using both SLP and FLP, be accomplished?

WE HAVE A LAUNCH DATE!

This should be the Aditya satellite, going up on the PSLV. Interesting though, that they are not being specific. We are left to guess a bit!

Now targeted for August/September

Quote
Crowded July-Aug for ISRO with Chandrayaan-3 ,PSLV, Gaganyaan abort missions; Aditya-L1 aimed for Aug-Sept

May 23, 2023

[...]

Soon after this, the space agency is aiming to launch Aditya-L1, India’s first solar observatory mission, in the August-September window.

[...]

So far as Aditya-L1 goes, the space agency has made significant progress and is confident of meeting the August-September window, not adhering to which could see the mission slip to the next calendar year.

https://indianexpress.com/article/cities/pune/unique-space-telescope-designed-pune-scientists-sun-mission-8667571/ [June 16, 2023]

Quote
The Solar Ultraviolet Imaging Telescope (SUIT), a unique space telescope developed by Pune’s Inter-University Center for Astronomy and Astrophysics (IUCAA), is now ready and has been delivered to the Indian Space Research Organisation (ISRO). The telescope is set to be integrated with the ADITYA-L1 mission, expected to be launched in mid-August this year.

Quote
“We had to build an ultra-clean room apart from ensuring that there will be no contamination from the particles scattered by the Sun on the payload. Special filters had to be designed to pick up the radiation,”

Quote
“SUIT, for the first time, will allow us to record images in this wavelength crucial for maintaining the Ozone and Oxygen content in the atmosphere of the Earth. SUIT will also measure the UV radiation hazardous for skin cancer.”

Quote
The SUIT project involved over 200-300 scientists over the last ten years. In addition to the initial grant of Rs 25 crore from ISRO for the hardware, scientists faced several challenges during the development of the payload, including building an ultra-clean room and designing special filters to capture the radiation.

Bengaluru: India’s first solar mission, Aditya-L1, is expected to be launched only by the end of August, while work on payload integration and testing has begun and the PSLV rocket is being readied for the launch.

Quote
Isro Chairman S Somanath told STOI: “We are expecting to launch Aditya by the end of August. Currently, payload integration and testing is going on.”

Quote
“We have to also add some additional payload tests to gain confidence. Some extended testing has been recommended on the payload side. All payloads have reached us, the PSLV [which will launch Aditya-L1] is already getting ready for an end of August launch,” Somanath said.

ISRO sources told TNIE that Aditya-L1 is tentatively scheduled for August 26 while the Vikram lander onboard Chandrayaan-3 will attempt soft landing on the moon around August 23-24. Officials said currently the final phase of Aditya-L1 payload integration and testing is underway. This will be India’s first mission to study the sun.

Support to additional ISRO missions

Chandrayaan-3 is just one of two ISRO missions that ESA will support this summer.

ISRO’s Aditya-L1 solar observatory is due to launch towards the end of August. Aditya-L1 is named after the Hindu Sun god and the spacecraft’s future home, L1 – the first Lagrange point of the Earth-Sun system. It will study a number of properties of our star, such as the dynamics and origins of coronal mass ejections.

The ESA support to Aditya-L1 will include similar tracking activities from Kourou and Goonhilly. But it will also include support from the largest of ESA’s antennas – the three 35-metre deep space antennas, located in New Norcia, Australia, Malargüe, Argentina, and Cebreros, Spain.

These stations are used by ESA every day to communicate with its expanding fleet of Solar System explorers such as Juice, BepiColombo and Solar Orbiter, and space observatories such as Gaia and the recently launched Euclid. They also support missions flown by ESA’s institutional and commercial partners.

ESA Flight Dynamics experts were also involved in the support to Aditya-L1. ESA assisted with the validation of the ‘orbit determination’ software that ISRO will use for the Aditya-L1 mission. This software is vital for calculating exactly where your spacecraft is in order to communicate with it and calibrate its scientific instruments.

Discussions are underway regarding potential ESA ground station support for India’s first human spaceflight programme, Gaganyaan.

Quote
After reaching the LEO, the satellite will be maneuvred using its onboard thrusters. “A series of earth burn elliptical orbital maneuvers is conducted to raise its orbit towards the L1 Lagrange point to surpass the earth's gravitational pull. The estimated time required to reach the L1 Lagrange point is around 109 days,” said Dr. T.N. Suresh Kumar, former senior scientist at ISRO.

Quote
Once the Aditya L1 mission reaches the L1 Lagrange point, it will be injected to a halo orbit. “A halo orbit is a type of orbit that allows the satellite to remain in a stable position between the Earth and the Sun. The satellite will use its onboard scientific instruments to study the dynamics of Sun's chromosphere and corona, its magnetic field, and its solar flares, solar wind etc. The data collected by the Aditya L1 mission will help scientists to understand better about the Sun and its impact on Earth,” Kumar told THE WEEK.
