Mars rules houses 3 and 10 for Aquarius rising — mildly malefic. The rules behind that verdict, dasha themes and how it compares with the other planets.
✦ Generate My Free Birth ChartFor Aquarius rising, Mars comes out net-challenging. It rules Aries (the 3rd house) and Scorpio (the 10th house), so its Mahadasha (7 years) concentrates on effort, courage and siblings and career and public standing.
Each rule below is applied in turn; the verdict is the sum. Positive numbers support the planet, negative ones weigh against it.
| Rule applied | Weight |
|---|---|
| Aries is the 3rd house (Trishadaya / upachaya); Aries is Mars's moolatrikona sign, so it counts 1.5× | -1.5 |
| Scorpio is the 10th house (Kendra) | 0.0 |
| Mars is a natural malefic owning the 10th (a kendra), which softens its malefic nature | +0.5 |
| The lagna lord Saturn regards Mars as a natural enemy | -0.5 |
| Net score → Mildly Malefic | -1.50 |
Aries — house 3 (Trishadaya / upachaya). The 3rd house governs effort, courage and siblings. Whatever Mars promises or withholds in a chart tends to be delivered through these matters. It is also the planet's moolatrikona sign.
Scorpio — house 10 (Kendra). The 10th house governs career and public standing. Whatever Mars promises or withholds in a chart tends to be delivered through these matters.

Rahu and Ketu own no signs, so they have no lordship to classify; they act through the sign lord of the sign they occupy and the planets they join (see Rahu & Ketu in KP).
In the Vimshottari system Mars's Mahadasha lasts 7 years out of the 120-year cycle. For Aquarius rising it activates the 3rd house (effort, courage and siblings) and the 10th house (career and public standing). Expect those areas to need extra care and effort; the sub-lords of the period and the transits at the time decide which way it actually goes. See Mars Mahadasha for the period itself.
Aquarius is a fixed sign, so its Badhaka (obstruction) house is the 9th, whose sign is Libra and whose lord is Venus. Mars is not the Badhaka lord. The Maraka lords for Aquarius rising are Jupiter (2nd) and Sun (7th); Mars is not one of them.
In KP astrology, ruling a house by sign is only the weakest of the four levels a planet can signify through (the others are occupying it and the star-lord links). A mildly malefic reading by lordship is useful context, but the sub-lord chain in the actual chart is what decides outcomes. See Significators in KP and Sub-Lord Theory.
