What they do

The startup tested an orbital-class satellite prototype with its Alchemy drug-crystallisation system using a stratospheric balloon at Hyderabad

Alchemy autonomously performed drug crystallisation in harsh near-space conditions and maintained crystal integrity during recovery

The mission validated core technologies for future orbital pharmaceutical manufacturing, including heat shields and avionics

Serendipity Space completed a near-space mission using a stratospheric balloon at the TIFR Balloon Facility in Hyderabad.
The mission tested an orbital-class satellite prototype that was operated and recovered successfully.
Its Alchemy system, an autonomous drug-crystallisation platform, ran continuously in harsh near-space conditions.
Alchemy performed drug crystallisation and maintained crystal integrity during controlled return, touchdown, and recovery.
The payload included commercial monoclonal antibody therapeutics, small molecules, and additional proteins for drug discovery.
The mission also tested core technologies for a future orbital fleet: advanced heat shield systems, avionics, and Alchemy.
The team designed and built the fully functional satellite prototype in under five months and completed a month-long test campaign.

The mission was inspired by Merck's development of an easier-to-inject version of cancer drug Keytruda in a microgravity lab on the International Space Station.
CEO Antariksh Parichha observed a cancer drug being administered intravenously over six to seven hours, leading him to explore drug formulation improvements.
India's space sector is seeing much activity, making it a good time to build such a startup.
Many existing drugs suffer poor bioavailability due to suboptimal crystal forms; high-concentration protein formulations are unstable under gravity.

Serendipity Space aims to set up pharmaceutical laboratories in space using reusable satellites to manufacture life-saving drugs under orbital conditions.
It plans to offer Low Earth Orbit (LEO)-based manufacturing services to pharmaceutical companies.
Alchemy is an autonomous pharmaceutical factory for manufacturing and processing drugs in microgravity, working with small-molecule drugs and protein-based therapeutics.
Microgravity enables superior drug crystal structures, improving solubility, stability, and effectiveness compared to Earth-based manufacturing.
Gravity on Earth disrupts crystallisation, causing defects; microgravity could enable uniform, stable formulations.
This could shift long IV infusions to simple at-home injections for protein-based therapies like monoclonal antibodies.
The technology was developed at the Institute of Life Sciences incubator in Bhubaneswar, where the startup is incubated.

The startup plans to undertake orbital missions next.
It aims to scale towards conducting orbital manufacturing and returning products to Earth.
