Vikram-1 (Skyroot Aerospace) and Indian Space Policy 2023

GS3 Science and Technology - SpacePrelims and Mains

Why in news
On 18 July 2026, Skyroot Aerospace's Vikram-1 reached Low Earth Orbit from Sriharikota on Mission Aagaman. It is India's first privately developed orbital launch vehicle to do so.
What it is
IN-SPACe is the single-window agency in the Department of Space that authorises and promotes private space activity. It works under the Indian Space Policy 2023, which follows the 2020 space sector reforms. The policy gives non-government entities access to ISRO facilities and the right to run end-to-end space activities.
Funding growth
Cumulative private funding rose from USD 100.5 million (2021-22) to USD 348.5 million (2023-24) and USD 618.5 million by 31 March 2026.
Screening of applications
Every private application is evaluated under IN-SPACe's Norms, Guidelines and Procedures (NGP), with strategic and security interests considered.
Financial support
Support includes a ₹1,000 crore Venture Capital Fund, a ₹500 crore Technology Adoption Fund and the IN-SPACe Seed Fund Scheme.
EO-PPP
The Earth Observation PPP is to build India's first privately owned Earth observation constellation, with about ₹1,200 crore private commitment.
POEM
The PSLV Orbital Experimental Module is a platform on which payloads, including private ones, fly on the PSLV's spent upper stage.
Payload capacity
Vikram-1 can place up to 350 kg into Low Earth Orbit.
Launch site and mission
It was launched as Mission Aagaman from the Satish Dhawan Space Centre, Sriharikota, and reached its designated Low Earth Orbit.
Technology features
It is India's first all-carbon composite orbital rocket. Its Orbital Adjustment Module is powered by a 100 per cent 3D-printed liquid engine.
Payloads
It carried experimental payloads, customer payloads and technology demonstrations, not dummy masses.
Role of IN-SPACe
IN-SPACe is the Department of Space body that authorises and promotes private space activity and gives access to ISRO facilities. It was created under the 2020 reforms.
Skyroot founders
Skyroot Aerospace was founded by Pawan Kumar Chandana and Bharath Daka.

Don’t confuse with IN-SPACe vs NSIL: IN-SPACe authorises and regulates private space activity. NSIL is ISRO's commercial arm that markets space products and services.

Don’t confuse with Vikram-S vs Vikram-1: Vikram-S was Skyroot's 2022 suborbital launch. Vikram-1 is its orbital small-satellite launch vehicle.

Science and technology: 57 Prelims questions since 2013; most test the concept behind the news, not the news itself. In Mains, 12 news-triggered questions.

White Rabbit Technology for Indian Standard Time dissemination

GS3 Science and TechnologyPrelims and Mains

Why in news
On 16 July 2026, Union Minister Pralhad Joshi commissioned a White Rabbit-based Indian Standard Time dissemination demonstration network at RRSL, Bengaluru. The release was posted on 18 July 2026.
What it is
White Rabbit is a technology that distributes very precise time and frequency over fibre-optic Ethernet networks. It extends the Precision Time Protocol with synchronous Ethernet and phase measurement to reach sub-nanosecond accuracy. It was first developed at CERN, and India is using it to spread national time from its reference clocks.
Where and when
The demonstration network was commissioned at the Regional Reference Standard Laboratory, Bengaluru, on 16 July 2026.
Who developed it
The Department of Consumer Affairs, CSIR-NPL and ISRO developed it jointly.
Verification link
Secure IST dissemination was verified between RRSL Bengaluru and NSE Chennai, with SEBI, NSE and BSNL as partners.
Target sectors
It is designed for banking and financial markets, telecom, power, transport, digital governance and other strategic infrastructure.
Initiative name
The project advances the government's One Nation, One Time initiative.
Origin of White Rabbit
White Rabbit was developed at CERN as an open-hardware project for accurate timing.

Don’t confuse with UTC (NPLI) vs UTC: UTC is the international time scale kept by BIPM. UTC (NPLI) is India's local realisation of it at CSIR-NPL, to which IST is traced.

Don’t confuse with Precision Time Protocol vs White Rabbit: PTP is the general network time-sync protocol. White Rabbit is an enhanced version that adds hardware measures for sub-nanosecond accuracy.

Science and technology: 57 Prelims questions since 2013; most test the concept behind the news, not the news itself. In Mains, 12 news-triggered questions.

No practice question for this one; the card may still help an answer. Why: New technology with a concept angle, but narrow demonstration network; Prelims question unlikely.

Worth revising until Prelims 2028: most news questions come within two years of the event.

ALMM List-II for solar PV cells

GS3 EnergyPrelims and Mains

Why in news
On 18 July 2026 the Ministry of New and Renewable Energy extended, till 31 December 2026, a limited exemption from ALMM List-II (solar PV cells) for net-metering and open access solar projects. The earlier deadline was 31 May 2026.
What it is
ALMM is a list of approved models and manufacturers of solar products kept by MNRE. Projects under government-linked schemes must use listed makers. List-I covers solar PV modules and List-II covers solar PV cells. It is meant to build domestic manufacturing and keep quality up.
New deadline
Net-metering and open access solar projects can commission without ALMM List-II (cells) till 31 December 2026.
Earlier deadline
The earlier dispensation for this segment ran only till 31 May 2026.
Policy stance
The policy on List-II is unchanged and there is no blanket extension for solar power projects.
Who gains
Standalone module makers get protection for inventories already built, through added demand, and time to shift to cells from List-II makers.
Who runs ALMM
ALMM is issued by the Ministry of New and Renewable Energy.

Don’t confuse with ALMM List-I vs List-II: List-I covers solar PV modules. List-II covers solar PV cells, the input used to make modules.

Don’t confuse with Net-metering vs open access: Net-metering lets a consumer export surplus rooftop power to the grid and offset the bill. Open access lets a consumer buy power from a third-party generator through the grid.

Economy terms and data: 42 Prelims questions since 2013, rising in recent years; they test what a term or instrument means. In Mains, 12 news-triggered questions.

No practice question for this one; the card may still help an answer. Why: Lasting solar manufacturing policy with a changed deadline. Economy is 13% of Prelims questions, but this is a narrow rule update.

Worth revising until Prelims 2028: most news questions come within two years of the event.
